  • Fig. 4 is an exploded perspective view illustrating the lighting unit 100.

  • the lighting unit 100 includes a casing 110 that has an accommodation space defined therein, a light outlet 111 formed in one surface thereof, and a pair of seating surfaces 112 and 113 spaced apart from each other in the accommodation space, substrates 121 and 122 that are seated on the respective seating surfaces 112 and 113 of the casing 110 while a plurality of LEDs are mounted on each of the substrates 121 and 122, radiation parts 130 and 140 that are respectively disposed outside the casing 110 at the formation positions of the seating surfaces 112 and 113, and a reflector 150 that is inserted into the casing 110 to reflect the light emitted from the substrates 121 and 122 for emission of the reflected light through the light outlet 111.
  • reference numeral 115 refers to a cover that covers the light outlet 111
  • reference numeral 116 refers to a frame that fixes the cover 115 to the light outlet 111
  • reference numeral 117 refers to a packing.
  • the casing 110 is a component formed integrally. Although the radiation parts 130 and 140 are illustrated as components independently of the casing 110 for convenience of description, but they are formed integrally with the casing 110.
  • the specific shape of the casing 110 may be changed, and the casing 110 may have any shape as long as the light outlet 111 is formed at one side thereof and a predetermined space is defined above the light outlet 111.
  • the pair of seating portions 112 and 113 are formed in the casing 110.
  • the seating portions 112 and 113 serve to fix the respective substrates 121 and 122, and the radiation parts 130 and 140 are respectively disposed outside the casing 110 at positions corresponding to the seating portions 112 and 113 within the casing 110 as described above.
  • the reason the plurality of seating portions 112 and 113 are formed is because, if LEDs are densely arranged on a single substrate for realization of high-power light sources, the densely arranged LEDs radiate high heat, in which case heat radiation efficiency is low when this heat is dissipated from a single radiation part.
  • the plurality of seating portions 112 and 113 are formed, the LEDs for realization of high power are distributed and mounted on the two substrates 121 and 122, and each of the radiation parts 130 and 140 is disposed to dissipate heat from an associated one of the substrates 121 and 122 to thereby enhance heat radiation efficiency.
  • heat since heat is easily dissipated, it is possible to prevent the life shortening of the LEDs.
  • the light emitted through the light outlet 111 has to be adjusted to be distributed suitable for the purpose of the lighting device.
  • the suitable distribution of light means light distribution that is limited by regulations or the like. That is, in a street light, it means light distribution pursuant to regulations on an intensity of illumination of a road surface and an irradiation range (area) of light.
  • the reflector 150 has a single plate shape, and has curved reflective portions 151 and 152, each reflecting the light emitted from an associated one of the substrates 121 and 122.
  • the reflector 150 has a divider 153 disposed between the curved reflective portions 151 and 152 to divide the space therebetween so that the light reflected from each of the curved reflective portions 151 and 152 may not be introduced into an opposite space.
  • Each of the curved reflective portions 151 and 152 defines a light reflection space that is convex upward from the light outlet 111, and it is possible to adjust the distribution of light emitted from the LEDs according to the curvatures and sizes of the curved reflective portions 151 and 152.
  • light distribution may be adapted by designing the reflector 150 in the state in which the specifications of the casing 110 and the output specifications of the LEDs are determined. Accordingly, although the specific configuration of the reflector 150 may be changed by other factors determining light distribution, the configuration of the reflector 150 may be consistent in that the number of curved reflective portions 151 and 152 must basically correspond to the number of substrates 121 and 122 and the divider 153 must be positioned between the reflection spaces defined by the respective curved reflective portions 151 and 152.
  • the casing 110 has an illumination sensor 172 that enables an intensity of illumination to be adjusted by controlling the power supplied from the power supply 250 to the substrates 121 and 122 according to the external illuminance, and has a communication element 171 that enables various types of control to be performed while communicating with the outside.
